Show 398 DR. J. E. GRAY ON THE FELIDAE. [Apr. -*-» bands and spots. Dr. Smith's specimen is much paler, yellow, with very indistinct rather darker yellow bands and spots, and very broad black bands on the legs. The large specimens from Tunis and Tangiers are very like the largest dark one from the Cape. A rather small specimen, received from Mr. Brandt of Hamburg as F. caligata from Africa, is only obscurely banded, is peculiar in the tail being black at the tip for about an inch, and in only having three or four very obscure narrow cross bands across the upper surface of the hinder two-thirds of the length of the tail. A small specimen, very obscurely banded and having a redder fur - with darker red streaks on the back, was received from Capt. Speke, marked "Menessa." The Felis caligata of Africa and the F. inconspicua of India are nearly allied and very similar; but one is grey and the other more fulvous and rather differently marked-so much so that I think they are distinct. They and Felis indica, the " Domestic Cat of India," differ from Felis chaus of India (and Africa?) in the greater length of the tail. The first two are almost always more or less distinctly banded and spotted, the F. chaus and F. indica being very obscurely (if at all) banded, except on the legs and thighs. I suspect that what have been called the African F. chaus may be only pale varieties of F. caligata; at least I have not seen any specimens of the true F. chaus from Africa. M. F. Cuvier's figures of F. chaus from Egypt are doubtful; for he describes the body and head as being 2 feet 4 inches long, and the tail 9 inches long; but the figure represents the tail as two-fifths, while the description represents it as being only one-fourth of the entire length. In the same manner the Chat aux oreilles rouges, figured by M . F. Cuvier, M a m m . Lithogr., from a specimen from India, is said to measure 24 inches from the end of the nose to the base of the tail, and its tail to measure 10 inches; and in the figure the tail is very nearly half the length of the head and body. Can both or either of these figures represent F. chaus, which is known by its short tail? I believe that all these African Cats are of one species, varying greatly in size and colour.
